Solve each quadratic equation by factoring and using the zero product property. 10x + 6 = -2x^2 -2

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
